Reshape polyester production with
antimony-free catalysts

Our new titanium-based catalyst solutions materialize Clariant's innovative approach to more sustainable polyester production. This advanced technology offers manufacturers a high-performance alternative to traditional antimony-based catalysts, delivering enhanced polymerization kinetics at lower processing temperatures. By enabling antimony-free PET production, the new catalysts address both growing supply chain challenges following China's export restrictions and increasing environmental concerns. The technology's water-stable formulation ensures consistent catalytic activity without risk of deactivation, resulting in superior polymer color, higher productivity, and reduced energy consumption. Designed for the entire polyester family including PET, PETG, PBT, and emerging polyesters like PEF, our catalyst solutions bring substantial CAPEX and OPEX savings while supporting manufacturers' efforts to lower their Scope 1 and 2 emissions. Ideal applications include beverage bottles, food packaging, textiles, and both mechanical and chemical PET recycling processes, helping brands meet evolving consumer demands and regulatory requirements.
